### 5/5 — Muy buena pero no esta en español

*2024-06-29*

Muy buena la app, los personajes están muy bonitos y es muy interactiva, pero estaria mejor si existiera la opción para cambiar el idioma a español :/, e igual no todos los cuadros de texto estan traducidos y hay un personaje que solo esta disponible en japonés. Fuera de eso 10/10
